Hi, I've done 3x1 portrait mode eyeinfinity on a ATI 6970 with 2 DVI + 1 mini Displayport option. This is like with windows 8.0 64 bit on ati 13.6 and 14.1 drivers i believe.
Now I upgraded to windows 8.1 and 14.4 drivers with a used 7970. I can't seem to do portrait mode eyeinfinitfy (3240x1920). Or more precisely no 3x1 portrait mode only 3x1 stacking (top and bottom) and 5760x1090 landscape mode. Please help. Reading a few other websites, seems like the option to change it is greyed out on CCC.
I was about to do 3240x1920 on windows but it only puts fullscreen on 1 of the 3 monitors. :( also full screen tabs puts them in 1 monitor instead of 3. Please help going to reinstall drivers for the 3rd time.
Here's screenshot of where I'm suppose to change it, it's greyed out.
